He survives a head wound
Miraculously survives
...maybe his brain matter is used in this way, using robotics.
Thinking aloud
Zechariah 11:17
“ Woe to the worthless shepherd, Who leaves the flock! A sword shall be against his arm And against his right eye; His arm shall completely wither, And his right eye shall be totally blinded.”
I wonder if his head wound still leaves him partially disabled even though he supposedly rises from the dead.
And my suspicion is a pistol bullet wound to the head is what causes his apparent death.
But you have a very plausible scenario- his brain matter implanted into a cyborg/robotic body is how he “survives/is resurrected”
